Well, it's obvious that ADFS supports the Adaptec board + ST412 drive -- 
that's what was in the original Acron winchester box (which, IIRC, hung 
off a Beeb), and what is used in the ACW. 

However, from what I can tell, the Filestore mever supported this (I 
don't know if it would work or not, I suspect not). The first Filestore 
hard disk unit -- the E20 -- was the same host adapter linked to a SCSI 
winchester.

I suspect the Adaptec board supports 256 byte sectors.

Oh, I have plenty (?) of 3.5" drives (and I suspect even modern 1.44M 
ones could be made to work in 720K mode). But I'd rather like to install 
the original type of drive if possible. Hence my other post asking for 
scrap Sony drive bits.
